RESUMO
BACKGROUND: Cast immobilization is the mainstay of treatment for stable pediatric supracondylar humeral fractures (SCHFs). In recent years, a waterproof and breathable hybrid-mesh (HM) cast has emerged and been marketed to address common complaints such as itch, skin irritation, and malodor. Hence, this randomized controlled trial seeks to assess the overall satisfaction, comfort, and clinical outcomes of using HM casts in the conservative treatment of stable pediatric SCHF. METHODS: Seventy-nine patients (age range: 1 to 10 y) with modified Gartland's classification Type I and Type IIa SCHF were recruited and randomized for immobilization with either fiberglass or HM long-arm cast for 3 weeks. During follow-up visits, patients were assessed for any loss of reduction and skin rash. The weight of casts, the presence of cast breakage, the duration of cast application, and removal were recorded. A self-reported patient comfort and satisfaction questionnaire was also administered during the same visit. RESULTS: The final analysis included 38 patients immobilized with fiberglass casts and 39 patients with HM casts. Despite the significantly longer duration required for HM cast removal (4.18±1.25 min vs. 2.25±0.55 min, P <0.001), the HM cast was significantly lighter than its fiberglass counterpart (162.82±23.94 g vs. 203.95±36.52 g, P <0.001). The HM casts have better comfort (4.05±0.887 vs. 3.47±0.951, P =0.007) and satisfaction (3.69±1.055 vs. 3.11±0.953, P =0.012) scores as compared to fiberglass casts for immobilizing pediatric SCHF without compromising clinical outcome. CONCLUSIONS: HM casts have better comfort and overall satisfaction as compared to conventional fiberglass casts for immobilizing pediatric SCHF without compromising clinical outcomes. LEVEL OF EVIDENCE: Level II-therapeutic studies-investigating the results of treatment.

PURPOSE: To determine if the novel 3D Machine-Vision Image Guided Surgery (MvIGS) (FLASH™) system can reduce intraoperative radiation exposure, while improving surgical outcomes when compared to 2D fluoroscopic navigation. METHODS: Clinical and radiographic records of 128 patients (≤ 18 years of age) who underwent posterior spinal fusion (PSF), utilising either MvIGS or 2D fluoroscopy, for severe idiopathic scoliosis were retrospectively reviewed. Operative time was analysed using the cumulative sum (CUSUM) method to evaluate the learning curve for MvIGS. RESULTS: Between 2017 and 2021, 64 patients underwent PSF using pedicle screws with 2D fluoroscopy and another 64 with the MvIGS. Age, gender, BMI, and scoliosis aetiology were comparable between the two groups. The CUSUM method estimated that the MvIGS learning curve with respect to operative time was 9 cases. This curve consisted of 2 phases: Phase 1 comprises the first 9 cases and Phase 2 the remaining 55 cases. Compared to 2D fluoroscopy, MvIGS reduced intraoperative fluoroscopy time, radiation exposure, estimated blood loss and length of stay by 53%, 62% 44%, and 21% respectively. Scoliosis curve correction was 4% higher in the MvIGS group, without any increase in operative time. CONCLUSION: MvIGS for screw insertion in PSF contributed to a significant reduction in intraoperative radiation exposure and fluoroscopy time, as well as blood loss and length of stay. The real-time feedback and ability to visualize the pedicle in 3D with MvIGS enabled greater curve correction without increasing the operative time.

BACKGROUND: The aim of this study is to compare the long-term functional outcome and quality of life between total knee arthroplasty (TKA) and fixed-bearing unicompartmental knee arthroplasty (UKA) for the treatment of isolated medial compartment osteoarthritis. METHODS: Between 2000 and 2008, a total of 218 patients underwent primary UKA at our tertiary hospital. A TKA group was matched through 1:1 propensity score matching and adjusted for age, gender, body mass index, preoperative knee flexion, and function scores. All patients had medial compartment osteoarthritis. The patients were assessed with the range of motion, Knee Society Knee Score and Knee Society Function Score, Oxford Knee Score, Short Form-36 physical component score (PCS) and mental component score preoperatively, at 6 months, 2 years, and 10 years. Patients' satisfaction, expectation fulfillment, and minimal clinically important difference were analyzed. RESULTS: There were no differences in baseline characteristics between groups after propensity score matching (P > .05). UKA had greater knee flexion at all time points. Although the Knee Society Function Score was superior in UKA by 5.5, 3, and 4.3 points at 6 months, 2 years, and 10 years, respectively (P < .001), these differences did not exceed the minimal clinically important difference (Knee Society Knee Score 6.1). There were no significant differences in the Oxford Knee Score and Short Form-36 physical component score/mental component score. At 10 years, similar proportions of UKA and TKA were satisfied (90.8% vs 89.9%, P = .44) and had expectation fulfillment (89.4% vs 88.5%, P = .46). Between 2 and 10 years, all function scores deteriorated significantly for both groups (P < .01). CONCLUSION: UKA and TKA are excellent treatment modalities for isolated medial compartment osteoarthritis, with similar functional outcomes, quality of life, and satisfaction at 10 years.

Horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare, autosomal recessive inherited disorder caused by mutations in ROBO3 gene. The clinical features of HGPPS include horizontal gaze palsy, progressive scoliosis, other oculomotor abnormalities such as strabismus and nystagmus. Whole-exome sequencing (WES) is used to diagnose rare Mendelian disorders, when routine standard tests have failed to make a formal pathological diagnosis. However, WES may identify variants of uncertain significance (VUS) that may add further ambiguity to the diagnosis. We report the case of a 4-year-old boy with horizontal gaze palsy, progressive scoliosis, microcephaly, and mild developmental delay. WES identified an intronic VUS in ROBO3 gene. We performed minigene splicing functional analysis to confirm the pathogenicity of this VUS. This report illustrates that WES data analysis with supportive functional analysis provides an effective approach to improve the diagnostic yield for unsolved clinical cases. This case also highlights the phenotypic heterogeneity in patients with HGPPS.
